Sixth man facing trial for tinnie plot

The last of six Victorian men arrested over an alleged plot to leave Australia by boat to become foreign fighters with Islamic State sympathisers has been ordered to stand trial.

Murat Kaya, 26, is accused of helping buy the boat that five other men were allegedly planning to use to leave Australia so they could join jihadist group Abu Sayyaf in the southern Philippines.

The defence had argued witnesses never directly identified Kaya as the boat's buyer, but Melbourne magistrate Charlie Rozencwajg on Tuesday said there was enough evidence to support a conviction and ordered that Kaya stand trial.

Mr Rozencwajg also refused Kaya's application for bail and said he had not proved any new exceptional circumstances since the last time he was refused bail.

Five other men have already been committed to stand trial.

Kadir Kaya, self-styled preacher Robert "Musa" Cerantonio, Paul Dacre, Antonio Granata and Shayden Thorne were committed to stand trial on May 19 after a week-long committal hearing in the Melbourne Magistrates' Court.

All six men face the same charge and have pleaded not guilty to making preparations for incursions into foreign countries to engage in hostile activities.
